DETAILED DESCRIPTION

Hereinafter, exemplary embodiments are described in detail withreference to the drawings as appropriate. However, detailed descriptionbeyond necessity may be omitted. For example, detailed description of amatter that has been already known well or overlapping description ofsubstantially the same configuration may be omitted. This is to avoidunnecessary redundancy of the following description and to facilitateunderstanding by those skilled in the art.

Note that the inventor of the present disclosure provides the attacheddrawings and the following description for those skilled in the art tofully understand the present disclosure, and do not intend to limit thesubject matter as described in the appended claims by these drawings anddescription.

Background of the Present Disclosure

As described in SUMMARY, various important information pieces arerecorded on an electronic device such as a notebook type computer.Accordingly, improvement of security against theft is demanded. If thedocking station described in above PTL 1 can lock the notebook typecomputer in the lock state, the notebook type computer cannot bedetached.

However, a notebook type computer in recent years is provided with acentral processing unit on a second casing side having a display. Afirst casing having a keyboard and the second casing having the displayand the central processing unit are separable, and the second casing canbe utilized as a tablet type computer. In a case where a techniquedescribed in PTL 1 is applied to this notebook type computer (theelectronic device), while the first casing is fixed to the dockingstation, the second casing, on which the important information piecesare recorded, is detachable.

Meanwhile, it is considered that a lock structure identical to a lockstructure of the first casing is also applied to the second casing,thereby making it impossible to detach the second casing. However, inthis case, a user must perform lock operation and unlock operation oneach of the first casing and the second casing.

Therefore, the present disclosure provides an electronic device capableof improving security against theft even in a case where a first casingand a second casing of the electronic device mounted on a mounting partare separable. Further, the present disclosure provides the electronicdevice capable of collectively locking and unlocking both of the firstcasing and the second casing.

Mounting part 11, on whichthe electronic device is mounted, is provided on an upper surface ofcasing 2 of mounting device 1. Moreover, as shown in FIG. 3 , lockmember 23 is locked to second casing 120 of electronic device 100 in astate in which electronic device 100 is mounted on mounting part 11, andthen cylinder lock 24 is operated to lock second casing 120.Accordingly, electronic device 100 cannot be detached from mountingdevice 1.

Mounting device 1 can be fixed to a vehicle with a fastening member suchas a bolt or a screw. The fixation with the fastening member may beperformed at a position where the fixation cannot be easily accessedfrom outside, or in a mode in which the fixation cannot be releasedunless dedicated tools are used. This makes it difficult to detachmounting device 1 itself from the vehicle. It should be noted thatmounting device 1 may be utilized not in the vehicle, but in a state inwhich mounting device 1 is fixed to a structure, a desk, or the like ata company or home.

[1-2-2. Configuration of Mounting Device]

As shown in FIG. 2 , mounting device 1 has the table shape. Mountingpart 11, on which electronic device 100 is mounted, is provided on theupper surface of casing 2 of mounting device 1. A plurality ofprojections 12 that protrudes upward is provided around mounting part 11such that projections 12 intermittently surround sides of first casing110 of electronic device 100 to be mounted.

Biasing projection member 13 is provided near a center in a widthdirection of mounting part 11. Biasing projection member 13 is supportedby casing 2 so as to be movable in the up and down direction between afirst position (a position shown in FIG. 2 ) and a second position. Atthe first position, an upper end of biasing projection member 13protrudes upward from the upper surface of mounting part 11 by apredetermined amount. At the second position, the upper end of biasingprojection member 13 is retreated downward from the upper surface ofmounting part 11. Biasing projection member 13 is biased to the firstposition side (upward) by a spring member (not shown). Biasingprojection member 13 and the spring member support lifting of theelectronic device upward when a user detaches the electronic deviceserving as a heavy object from mounting part 11.

Lock mechanism 20 is provided on a right side of mounting part 11. Lockmechanism 20 locks and fixes electronic device 100 in a state in whichelectronic device 100 is mounted on mounting part 11.

As shown in FIG. 3 , in a state in which electronic device 100 ismounted on mounting device 1, first casing 110 of electronic device 100is intermittently surrounded by the plurality of projections 12 disposedaround mounting part 11. As a result, movement of first casing 110 inthe right and left direction and a front and rear direction is regulatedin the mounted state. In other words, first casing 110 of electronicdevice 100 can be mounted on mounting part 11 only in a predeterminedpositional relation.

Further, lock member 23 described below is locked to a right side in adevice width direction of second casing 120 of electronic device 100mounted on mounting device 1. As a result, when lock member 23 is lockedto second casing 120 in the state in which electronic device 100 ismounted on mounting device 1, lock member 23 regulates movement ofsecond casing 120 in the up and down direction and the front and reardirection. Further, in second casing 120, lower side 120S is fitted tothe socket, and front and rear sides and right and left sides of lowerside 120S are covered with socket 130. With this configuration, movementof second casing 120 in the device width direction (the right and leftdirection) is also regulated. Therefore, movement of electronic device100 in any direction is regulated.

[1-2-3. Lock Mechanism]

As shown in FIG. 2 , lock mechanism 20 has movable projection member 21,operating member 22, lock member 23, and cylinder lock 24. Further, lockmechanism 20 has a moving mechanism that drives lock member 23 accordingto movement of movable projection member 21, operating member 22, lockmember 23, and cylinder lock 24. Before describing these configurations,description is first given of a lock structure between lock member 23 ofmounting device 1 and second casing 120 of electronic device 100.

[1-2-4. Lock Structure Between Lock Member of Mounting Device and SecondCasing of Electronic Device]

FIG. 4 is an enlarged perspective view of locked holes of the electronicdevice according to the first exemplary embodiment of the presentdisclosure (an enlarged perspective view of a portion shown by arrow Din FIG. 1A). As shown in FIG. 4 and aforementioned FIG. 1B, secondcasing 120 of the electronic device has locked hole 120 a at a lowerpart on the right side. Further, socket 130 of first casing 110 of theelectronic device has locked hole 130 a at an upper part on a rightside. Locked hole 120 a of second casing 120 and locked hole 130 a ofsocket 130 are formed at an overlapping position in a state in whichsecond casing 120 is attached to socket 130, as seen in a directionparallel to rotating axial center AX (see FIGS. 6A and 6B) of hinge 140.

FIGS. 5A and 5B are side views of a portion near lock member 23 of themounting device. FIGS. 6A and 6B are front views of the portion nearlock member 23 of the mounting device.

Lock member 23 is configured by casing 2 such that lock member 23 isrotatable around second shaft 37 that extends in the device widthdirection. Lock member 23 is rotatable between an initial position and alocked hole side position in the state in which electronic device 100 ismounted on mounting device 1. Rotating axial center AY of second shaft37 is located on an extension line of rotating axial center AX of hinge140. In other words, rotating axial center AY of second shaft 37 iscoaxial with rotating axial center AX of hinge 140.

Further, lock member 23 is movable parallel to a direction of rotatingaxial center AY of second shaft 37. Lock member 23 is biased in adirection in which lock member 23 rotates counterclockwise around secondshaft 37, as seen from a right side surface of mounting device 1.

Lock member 23 has main body 23 a, lock projection 23 b, and abuttingpart 23 c.

Main body 23 a has a lever shape and is rotatably supported by secondshaft 37 on one end side.

Lock projection 23 b is a projection that protrudes from a side surfaceon an inner side in the device width direction of main body 23 a to theinner side in the device width direction. Lock projection 23 b has ashape and a size capable of locking to locked hole 120 a of secondcasing 120 and locked hole 130 a of socket 130.

Abutting part 23 c extends from an end on the inner side in the devicewidth direction and a rear side of main body 23 a in the device widthdirection.

When lock member 23 rotates around second shaft 37, abutting part 23 cabuts on a back surface of second casing 120. At this time, lockprojection 23 b of lock member 23 is located on an outer side in thedevice width direction of locked hole 120 a of second casing 120 andlocked hole 130 a of socket 130. In this state, cylinder lock 24 isrotated to a lock state by utilizing a key. Then, abutting part 23 cmoves to the inner side in the device width direction, and lockprojection 23 b of lock member 23 is locked to locked hole 120 a ofsecond casing 120 and locked hole 130 a of socket 130.

As described above, lock mechanism 20 has movable projection member 21,operating member 22, lock member 23, cylinder lock 24, and the movingmechanism.

Movable projection member 21 is provided to be movable in the up anddown direction between an upward protruding position and a retreatingposition within an up-and-down through-hole formed in mounting part 11.The “upward protruding position” is a position at which an upper end ofmovable projection member 21 protrudes upward from the upper surface ofmounting part 11 by a predetermined amount (a position shown in FIG. 2). The “retreating position” is a position at which movable projectionmember 21 retreats downward from the upper surface of mounting part 11.Movable projection member 21 has, on a rear side, vertical wall 21 adirected to the rear side.

Operating member 22 is provided movably in the front and rear direction.Operating member 22 is a member operated by a user when lock member 23is rotated from the locked hole side position or the other position tothe initial position, that is, when lock member 23 is returned to theinitial position. The “locked hole side position” is a rotationalposition around second shaft 37 of lock member 23, shown in FIG. 5B. Atthe “locked hole side position”, locked hole 120 a of second casing 120and locked hole 130 a of socket 130 of electronic device 100 mounted onmounting part 11 overlap with lock projection 23 b of lock member 23, asseen from one end in the device width direction. The “locked hole sideposition” is changed according to a rotational position of second casing120 of electronic device 100. When lock member 23 is moved in the devicewidth direction (the right and left direction) while lock member 23 islocated at the locked hole side position, lock projection 23 b of lockmember 23 can be locked to locked hole 120 a of second casing 120 andlocked hole 130 a of socket 130. The “initial position” is a rotationalposition around second shaft 37 of lock member 23, shown in FIG. 5A. Atthe “initial position”, lock member 23 is fallen to a rear side ofsecond shaft 37 at an angle of about 90 degrees with respect to the upand down direction, and cannot be rotated clockwise any further (whenthe left side is seen from the right side in the device widthdirection). Since vertical wall 21 a of movable projection member 21abuts on a front end of gear member 32 described below, the lock member23 cannot be rotated.

Cylinder lock 24 is a lock capable of rotating second shaft 37 by 90degrees by inserting a corresponding key.

The moving mechanism has a first moving mechanism, a second movingmechanism, and a third moving mechanism. The first moving mechanism is amechanism that moves lock member 23 to the locked hole side positionbased on movement of movable projection member 21 in the up and downdirection. The second moving mechanism is a mechanism that moves lockmember 23 to the initial position based on movement of operating member22 in the front and rear direction. The third moving mechanism is amechanism that moves lock member 23 between the locked hole sideposition and a lock position in the device width direction according tolocking operation using the key corresponding to cylinder lock 24.

[1-3. Interlocking Lock Mechanism of Second Unit]

In the interlocking lock mechanism, whenlock projection 23 b of lock member 23 is inserted in locked holes 130a, 120 a respectively provided on the right sides of socket 130 andsecond unit 102, a left side of second unit 102 is also locked to a leftside of socket 130. Details are described below.

FIG. 7 is a sectional view of socket 130 of first unit 101 taken alongline 7-7 in FIG. 1A. As shown in FIG. 7 and aforementioned FIGS. 1B and1C, socket 130 of first unit 101 has locked hole 130 a on a right sidesurface and locked hole 130 b on a left side surface. Locked projection130 c that protrudes to an inner side of socket 130 is formed on anupper end side of locked hole 130 b on the left side surface. It shouldbe noted that locked projection 130 c is provided in the presentexemplary embodiment. However, if locked projection 130 c is provided,locked hole 130 b is not essential.

FIG. 8 is a view showing a configuration of the interlocking lockmechanism of second unit 102 in the electronic device according to thefirst exemplary embodiment of the present disclosure. FIG. 8 is asectional view of the second unit taken along line 7-7 in FIG. 1A.

Second casing 120 of second unit 102 has outside casing 151 and casingbody 152. Outside casing 151 covers a side of casing body 152. Outsidecasing 151 is, for example, formed of resin. Second casing 120 is, forexample, formed of magnesium alloy.

Second unit 102 has locked holes 120 a on a lower side of each of rightand left sides. Locked holes 120 a is formed in outside casing 151 thatconfigures second casing 120.

Further, recesses 152 a, 152 b are formed by respectively cutting awaythe lower sides of the right and left sides of casing body 152 thatconfigures second casing 120. Oscillation member 210 and spring 220 aredisposed in each of recesses 152 a, 152 b.

Further, casing body 152 is formed with groove 152 c that extends in theright and left direction. Bar-shaped member 230 is disposed in groove152 c so as to be movable in the right and left direction.

Here, socket 130 of the electronic device of the present exemplaryembodiment is capable of housing second unit 102 even in a state inwhich any principal surface of second unit 102 faces the front.Accordingly, right and left oscillation members 210 and springs 220 havea bilaterally symmetrical structure. Therefore, oscillation members 210and springs 220 on one of right and left sides are mainly described, anddescription of oscillation members 210 and springs 220 on the other sideis appropriately omitted. Oscillation member 210 and spring 220 on theleft side are described herein.

Oscillation member 210 has base end 210 a, abutting part 210 b, lockpawl 210 c, tip 210 d, and spring lock projection 210 e.

Supporting shaft 221 formed in supporting base 152 d of casing body 152is inserted in base end 210 a. With this configuration, oscillationmember 210 is supported by supporting shaft 221 so as to be swingablearound supporting shaft 221. FIG. 8 shows a state in which oscillationmember 210 is located at a reference position by biasing force of spring220.

Abutting part 210 b extends from a vicinity of base end 210 a to lockedhole 120 a side. When oscillation member 210 is located at the referenceposition, abutting part 210 b is located near locked hole 120 a on adevice inner side with respect to locked hole 120 a.

Spring 220 has base end 220 a, first spring 220 b, and second spring 220c. Spring 220 is fixed to supporting base 152 d at base end 220 a. Firstspring 220 b and second spring 220 c are respectively pressed to springlock projection 210 e of oscillation member 210 from right and left,thereby sandwiching spring lock projection 210 e of oscillation member210 from right and left. Spring 220 biases oscillation member 210 so asto press tip 210 d of oscillation member 210 against bar-shaped member230. It should be noted that the biasing forces of right and leftsprings 220 are identical or substantially identical. With thisconfiguration, right and left oscillation members 210 are kept at thereference positions shown in FIG. 8 in a state in which bar-shapedmember 230 is sandwiched from right and left.

According to the present exemplary embodiment, in the state in whichelectronic device 100 is mounted on mounting device 1, first casing 110of electronic device 100 is intermittently surrounded by the pluralityof projections 12 disposed around mounting part 11. As a result,movement of first casing 110 in the right and left direction and thefront and rear direction is regulated in the mounted state.

Further, in the state in which electronic device 100 is mounted onmounting device 1, when lock member 23 is locked to second casing 120,movement of second casing 120 in the front and rear direction and the upand down direction is regulated by lock member 23. Moreover, in secondcasing 120, lower side 120S is fitted to socket 130, and front and rearsides and right and left sides of lower side 120S are covered withsocket 130. Accordingly, movement of second casing 120 in the right andleft direction is also regulated.

Therefore, in the state in which electronic device 100 is mounted onmounting device 1, when lock member 23 is locked to second casing 120,both first casing 110 and second casing 120, that is, entire electronicdevice 100, cannot be moved from mounting device 1.

Moreover, in the present exemplary embodiment, when lock member 23 islocked to second casing 120, movement of lock member 23 in the devicewidth direction is locked by operating cylinder lock 24 described belowwith the key. Therefore, lock member 23 cannot be manually unlocked.Hence, a third person other than the user cannot detach and take awaythe electronic device from mounting device 1, thereby improving securityagainst theft.

Particularly, in the present exemplary embodiment, since interlockinglock mechanism 200 is provided in electronic device 100, the followingaction can be obtained. The action will be described with reference toFIG. 11 . In other words, in the state in which second unit 102 isattached to socket 130, when lock projection 23 b of lock member 23 ofmounting device 1 is inserted through right locked hole 130 a of socket130 and right locked hole 120 a of second unit 102, lock projection 23 babuts on abutting part 210 b of right oscillation member 210. When lockprojection 23 b further enters the device inner side (the left side),abutting part 210 b of right oscillation member 210 is pressed to thedevice inner side of second unit 102 by lock projection 23 b. With thisconfiguration, right oscillation member 210 oscillates counterclockwise.As a result, bar-shaped member 230 moves to the left, and further, leftoscillation member 210 oscillates counterclockwise. At this time, lockpawl 210 c of left oscillation member 210 moves below locked projection130 c on the left side surface of socket 130. With this configuration,second unit 102 is locked to socket 130 such that the left side cannotbe lifted upward.

In this way, according to electronic device 100 of the present exemplaryembodiment, second unit 102 is locked to lock projection 23 b of lockmember 23 along with socket 130 on the right side. Accordingly, theright side of second unit 102 cannot be lifted upward with respect tolock member 23 (mounting device 1) and socket 130 (first unit 101).Further, second unit 102 is locked to socket 130 on the left side.Accordingly, the left side cannot be lifted upward with respect tosocket 130 (first unit 101). In other words, both the right and leftsides of second unit 102 cannot be lifted upward with respect to socket130. Accordingly, security against theft further improves.

Further, in electronic device 100 of the present disclosure, whenelectronic device 100 is locked to mounting device 1, it is no longernecessary for the user to perform lock operation on each of first unit101 and second unit 102. Therefore, convenience of the user improves.

Further, since the right and left sides are locked, strength of thelocking can be improved. Unlike the present exemplary embodiment, in aconfiguration in which only one side is locked, when another side isstrongly lifted, lock projection 23 b of lock member 23 can be broken.In this case, second unit 102 can be detached. However, such breakagedoes not occur in electronic device 100 of the present exemplaryembodiment.

[2. Effects Etc.]

Electronic device 100 of the present exemplary embodiment includes firstunit 101 having the input part and second unit 102 having the display,and first unit 101 and second unit 102 are detachably coupled. Firstunit 101 includes socket 130 capable of housing a predetermined side ofsecond unit 102. Locked holes 130 a, 120 a (insertion holes), into whichlock projection 23 b (a security member) of lock member 23 can beinserted, are provided on one of the right and left sides of socket 130and second unit 102.

Interlocking lock mechanism 200 is provided on another of the right andleft sides of socket 130 and second unit 102. Interlocking lockmechanism 200 locks second unit 102 to socket 130 when lock projection23 b (the security member) of lock member 23 is inserted into lockedholes 130 a, 120 a (the insertion holes).

With this configuration, in electronic device 100 of the presentexemplary embodiment, when lock projection 23 b (the security member) oflock member 23 is inserted into locked holes 130 a, 120 a (the insertionholes) provided on the one side of socket 130 and second unit 102,second unit 102 can be locked to socket 130 on these two right and leftsides. Therefore, strength of locking can be improved more than a casewhere second unit 102 is locked to socket 130 on one side. Further,security against theft can be improved in the electronic device in whichfirst unit 101 and second unit 102 are separable.

Further, in electronic device 100 of the present disclosure, whenelectronic device 100 is locked to mounting device 1, it is no longernecessary for the user to perform lock operation on each of first unit101 and second unit 102. Therefore, convenience of the user improves.

In the present exemplary embodiment, interlocking lock mechanism 200 haslocked projection 130 c (a lock part), a bar-shaped member 230, and lockpawl 210 c (a lock member). Locked projection 130 c is provided on theother of the right and left sides of socket 130. Bar-shaped member 230is provided in second unit 102, and is displaced when lock projection 23b (the security member) of lock member 23 is inserted into locked holes130 a, 120 a (the insertion holes). Lock pawl 210 c (the lock member) islocked to locked projection 130 c (the lock part) of socket 130 whenbar-shaped member 210 is displaced.

With this configuration, interlocking lock mechanism 200 can be realizedwith a simple configuration by bar-shaped member 230 and lock pawl 210 c(the lock member).

Other Exemplary Embodiments

As above, the first exemplary embodiment is described as an illustrationof a technique disclosed in the present application. However, thetechnique in the present disclosure is not limited to this firstexemplary embodiment, and is also applicable to exemplary embodimentsthat are appropriately changed, replaced, added, omitted, or the like.Further, a new exemplary embodiment can be implemented by combining therespective components explained in the above-described first exemplaryembodiment.

In the above-described exemplary embodiment, abutting part 210 b andlock pawl 210 c of oscillation member 210 are integrally formed inoscillation member 210. However, a portion of abutting part 210 b andlock pawl 210 c of oscillation member 210 may be separated from theother portion of oscillation member 210. In this case, for example, aspring that can be biased in the device width direction may be providedbetween an oscillation member and a member that configures an abuttingpart and a lock pawl. A positional relation in the device widthdirection between the oscillation member and the member that configuresthe abutting part and the lock pawl can be changed. With thisconfiguration, for example, even in a case where a type of mountingdevice is changed, and an insertion amount of a lock projection of alock member into the locked holes of the second unit is increased, whenthe lock pawl on the other side abuts against an inner surface of thecasing, the lock pawl on the other side is not strongly pressed againstthe inner surface of the casing while the oscillation member oscillates.Hence, for example, even in the case where the type of mounting deviceis changed, breakage of the lock pawl or interlocking lock mechanism 200is prevented.

In the above-described exemplary embodiment, lock projection 23 bincluded in mounting device 1 is described as an example of the securitymember. However, the technique in the present disclosure is not limitedto this lock projection. A lock projection included in a member, calledKensington lock or security wire lock, can be utilized as the securitymember.
